DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The embodiments of a zipper head assembly structure of the present disclosure are described. Other advantages and objectives of the present disclosure can be easily understood by one skilled in the art from the disclosure. The present disclosure can be applied in different embodiments. Various modifications and variations can be made to various details in the description for different applications without departing from the scope of the present disclosure. The drawings of the present disclosure are provided only for simple illustrations, but are not drawn to scale and do not reflect the actual relative dimensions. The following embodiments are provided to describe in detail the concept of the present disclosure, and are not intended to limit the scope thereof in any way.

First Embodiment

Referring to FIG. 1 to FIG. 8, one of the embodiments of the present disclosure provides a sliding assembly 1 (such as a sliding head or a slide fastener head), and the sliding assembly 1 includes a base portion 10, a first lateral wall portion 11, a second lateral wall portion 12, a seat portion 13, a retaining member 14 (such as a hook body or a horse-like hook), and an elastic member 15. The base portion 10, the first lateral wall portion 11, the second lateral wall portion 12 and the seat portion 13 are mated with each other to form a sliding member A.

Referring to FIG. 1, FIG. 7 and FIG. 8, the first lateral wall portion 11 and the second lateral wall portion 12 extend respectively upwardly from two opposite lateral sides of the base portion 10, and the first lateral wall portion 11 and the second lateral wall portion 12 correspond to each other and are connected to a front side portion 101 of the base portion 10. In addition, the seat portion 13 is disposed on the base portion 10 and is connected to a rear side portion 102 of the base portion 10, and the seat portion 13 has a positioning through hole 130 formed between the first lateral wall portion 11 and the second lateral wall portion 12. Moreover, the elastic member 15 is disposed on the seat portion 13 to elastically abut against the retaining member 14, and the elastic member 15 has a fixing portion 151 fixed on the seat portion 13, an elastic portion 152 extending from the fixing portion 151, and an abutting portion 153 extending from the elastic portion 152 for abutting against the retaining member 14. Furthermore, the retaining member 14 is movably disposed on the seat portion 13 for movably contacting the abutting portion 153 of the elastic member 15, and the retaining member 14 has a positioning portion 140 disposed on an end portion thereof for passing through the positioning through hole 130, and the retaining member 14 has a retaining portion 141 disposed on another end thereof.

Referring to FIG. 1, FIG. 2 and FIG. 8, the seat portion 13 has at least one retaining block 133 and at least one through opening 134 adjacent to the at least one retaining block 133, and the at least one retaining block 133 has an inner surface 1330 extending inwardly from an inner surface 13002 of the seat portion 13. In addition, the inner surface 1330 of the at least one retaining block 133 is inclined at an adjustable angle θ relative to the inner surface 13002 of the seat portion 13, and the at least one retaining block 133 has a top side surface 1331, a bottom side surface 1332 opposite to the top side surface 1331, and a front surface 1333 connected between the top side surface 1331 and the bottom side surface 1332. Therefore, the retaining portion 141 can be restricted or limited by the bottom side surface 1332 of the at least one retaining block 133 and can be movably retained on a predetermined plane without being changed by a change of the adjustable angle θ. That is to say, no matter how the adjustable angle θ is adjusted or changed (for example, the adjustable angle θ would be adjusted or changed by a too small or too large punching force), the retaining portion 141 can be restricted by the bottom side surface 1332 of the at least one retaining block 133 and can be movably retained on a predetermined plane without being changed by a change of the adjustable angle θ (that is to say, the retaining portion 141 can continuously contact the bottom side surface 1332 of the at least one retaining block 133 and can be rotated relative to the inner surface 13002 of the seat portion 13), so that the retaining portion 141 cannot be offset when the adjustable angle θ is adjusted or changed due to the adjustable angle θ being changed or adjusted on a horizontal plane (not on a vertical plane).

For example, as shown in FIG. 2, the seat portion 13 has at least one outer groove 13A formed on an outer surface 13001 thereof, the seat portion 13 has at least one inner groove 13B formed on the inner surface 13002 thereof, and the at least one retaining block 133 extends inwardly from the at least one outer groove 13A and the at least one inner groove 13B. In other words, the at least one outer groove 13A and the at least one inner groove 13B can be respectively formed on the outer surface 13001 and the inner surface 13002 of the seat portion 13 in advance, so that the thickness between the outer surface 13001 and the inner surface 13002 of the seat portion 13 can be decreased. Therefore, the at least one retaining block 133 and the at least one through opening 134 can be concurrently formed by a dotting or punching machine easily due to the decreased thickness between the outer surface 13001 and the inner surface 13002 of the seat portion 13. However, the foregoing example is not meant to limit the scope of the present disclosure. For another example, the at least one inner groove 13B can be omitted, so that the at least one retaining block 133 only extends inwardly from the at least one outer groove 13A. Alternatively, the at least one outer groove 13A can be omitted, so that the at least one retaining block 133 only extends inwardly from the at least one inner groove 13B.

It should be noted that a thickness h2 of the elastic portion 152 is smaller than a thickness h1 of the fixing portion 151 as shown in FIG. 4, such that an elastic coefficient and an elastic force provided by the elastic portion 152 can be increased. Therefore, the elastic portion 152 can avoid causing elastic fatigue and plastic deformation so as to increase the usage life of the elastic member 15. In addition, referring to FIG. 4, FIG. 6 and FIG. 8, the abutting portion 153 has an inclined chamfer 1530 formed on an end thereof for slidably contacting the retaining member 14 so as to increase a contact area between the abutting portion 153 and the retaining member 14.

More particularly, referring to FIG. 1, FIG. 5 and FIG. 6, the fixing portion 151 has a front fixing section 1511, a rear fixing section 1512 connected to the elastic portion 152, and a middle fixing section 1513 connected between the front fixing section 1511 and the rear fixing section 1512. With regard to a width of the elastic member 15, as shown in FIG. 5, a width W12 of the rear fixing section 1512 is smaller than a width W11 of the front fixing section 1511, and a width W13 of the middle fixing section 1513 is decreased gradually from the front fixing section 1511 to the rear fixing section 1512. As shown in FIG. 6, a width W2 of the elastic portion 152 is much smaller than the width W12 of the rear fixing section 1512, such that an elastic coefficient and an elastic force provided by the elastic portion 152 can be increased. Therefore, the elastic portion 152 can avoid causing elastic fatigue and plastic deformation so as to increase the usage life of the elastic member 15. In addition, a width W3 of the abutting portion 153 is larger than a width W2 of the elastic portion 152 so as to increase a contact area between the elastic member 15 and the retaining member 14.

More particularly, referring to FIG. 1 and FIG. 4, the rear fixing section 1512 has a first fixing section 15121 connected to the middle fixing section 1513 and a second fixing section 15122 connected between the first fixing section 15121 and the elastic portion 152. With regard to a thickness of the elastic member 15, as shown in FIG. 4, a thickness h2 of the elastic portion 152 is smaller than a thickness h11 of the first fixing section 15121 and a thickness h12 of the second fixing section 15122 of the rear fixing section 1512, and the thickness h12 of the second fixing section 15122 is decreased gradually from the first fixing section 15121 to the elastic portion 152. In addition, a thickness h2 of the elastic portion 152 and a thickness h3 of the abutting portion 153 are substantially the same.

More particularly, referring to FIG. 1 and FIG. 3, the seat portion 13 has a front retaining section 1301 for fixing the front fixing section 1511, a rear retaining section 1302 for fixing the rear fixing section 1512, and a middle retaining section 1303 connected between the front retaining section 1301 and the rear retaining section 1302 for fixing the middle fixing section 1513. In addition, as shown in FIG. 3, a width W2′ of the rear retaining section 1302 is smaller than a width W1′ of the front retaining section 1301, and a width W3′ of the middle retaining section 1303 is decreased gradually from the front retaining section 1301 to the rear retaining section 1302. The width W3′ of the middle retaining section 1303 and the width W2′ of the rear retaining section 1302 are smaller than the width W1′ of the front retaining section 1301, so that the friction force between the seat portion 13 and a piece of clothing can be decreased so as to increase the smooth level of the sliding assembly 1 slidably mated with the clothing.

More particularly, referring to FIG. 7 and FIG. 8, the retaining portion 141 in a first receiving groove 131 can be restricted or limited by the bottom side surface 1332 of the at least one retaining block 133 and can be movably retained on a predetermined plane, so that the retaining member 14 can be moved upwardly (as shown in FIG. 11) or downwardly (as shown in FIG. 10) relative to the retaining portion 141 as a rotating shaft or a rotation axis.

Referring to FIG. 1 and FIG. 9 to FIG. 11, one of the embodiments of the present disclosure provides a zipper head assembly structure Z. The zipper head assembly structure Z includes a sliding assembly 1 and a pulling member 2 (such as a pull tab or a pull piece). The sliding assembly 1 includes a base portion 10, a first lateral wall portion 11, a second lateral wall portion 12, a seat portion 13, a retaining member 14 and an elastic member 15. The first lateral wall portion 11 and the second lateral wall portion 12 extend respectively upwardly from two opposite lateral sides of the base portion 10, and the first lateral wall portion 11 and the second lateral wall portion 12 correspond to each other and are connected to a front side portion 101 of the base portion 10. In addition, the seat portion 13 is disposed on the base portion 10 and is connected to a rear side portion 102 of the base portion 10, and the seat portion 13 has a positioning through hole 130 formed between the first lateral wall portion 11 and the second lateral wall portion 12. Moreover, the elastic member 15 is disposed on the seat portion 13 to elastically abut against the retaining member 14, and the elastic member 15 has a fixing portion 151 fixed on the seat portion 13, an elastic portion 152 extending from the fixing portion 151, and an abutting portion 153 extending from the elastic portion 152 for abutting against the retaining member 14. Furthermore, the retaining member 14 is movably disposed on the seat portion 13 for movably contacting the abutting portion 153 of the elastic member 15, and the retaining member 14 has a positioning portion 140 disposed on an end portion thereof for passing through the positioning through hole 130. In addition, the pulling member 2 is movably mated with the retaining member 14, for example, the pulling member 2 includes a movable piece 21 disposed on an end portion 20 thereof for movably mating with the retaining member 14.

Second Embodiment

Referring to FIG. 12 to FIG. 19, one of the embodiments of the present disclosure provides a sliding assembly 1 (such as a sliding head or a slide fastener head), and the sliding assembly 1 includes a base portion 10, a first lateral wall portion 11, a second lateral wall portion 12, a seat portion 13, a retaining member 14 (such as a hook body or a horse-like hook), and an elastic member 15. The base portion 10, the first lateral wall portion 11, the second lateral wall portion 12 and the seat portion 13 are mated with each other to form a sliding member A.

Referring to FIG. 12, FIG. 18 and FIG. 19, the first lateral wall portion 11 and the second lateral wall portion 12 extend respectively upwardly from two opposite lateral sides of the base portion 10, and the first lateral wall portion 11 and the second lateral wall portion 12 correspond to each other and are connected to a front side portion 101 of the base portion 10. In addition, the seat portion 13 is disposed on the base portion 10 and is connected to a rear side portion 102 of the base portion 10, and the seat portion 13 has a positioning through hole 130 formed between the first lateral wall portion 11 and the second lateral wall portion 12. Moreover, the elastic member 15 is disposed on the seat portion 13 to elastically abut against the retaining member 14, and the elastic member 15 has a first fixing portion 151 fixed on the seat portion 13, a second fixing portion 154 fixed on the seat portion 13, an exposed portion 155 connected between the first fixing portion 151 and the second fixing portion 154 and exposed out of the seat portion 13 (or exposed from the seat portion 13), an elastic portion 152 extending from the first fixing portion 151, and an abutting portion 153 extending from the elastic portion 152 for abutting against the retaining member 14. Furthermore, the retaining member 14 is movably disposed on the seat portion 13 for movably contacting the abutting portion 153 of the elastic member 15, and the retaining member 14 has a positioning portion 140 disposed on an end portion thereof for passing through the positioning through hole 130. It should be noted that the retaining member 14 has a uniform thickness H, and the positioning portion 140 of the retaining member 14 has a cutting edge 1400 (such as a cutting plane) formed on a lateral surface thereof.

Referring to FIG. 12, FIG. 13 and FIG. 19, the seat portion 13 has at least one retaining block 133 and at least one through opening 134 adjacent to the at least one retaining block 133, and the at least one retaining block 133 has an inner surface 1330 extending inwardly from an inner surface 13002 of the seat portion 13. In addition, the inner surface 1330 of the at least one retaining block 133 is inclined at an adjustable angle θ relative to the inner surface 13002 of the seat portion 13, and the at least one retaining block 133 has a top side surface 1331, a bottom side surface 1332 opposite to the top side surface 1331, and a front surface 1333 connected between the top side surface 1331 and the bottom side surface 1332. Therefore, the retaining portion 141 can be restricted or limited by the bottom side surface 1332 of the at least one retaining block 133 and can be movably retained on a predetermined plane without being changed by a change of the adjustable angle θ. That is to say, no matter how the adjustable angle θ is adjusted or changed (for example, the adjustable angle θ would be adjusted or changed by a too small or too large punching force), the retaining portion 141 can be restricted by the bottom side surface 1332 of the at least one retaining block 133 and can be movably retained on a predetermined plane without being changed by a change of the adjustable angle θ (that is to say, the retaining portion 141 can continuously contact the bottom side surface 1332 of the at least one retaining block 133 and can be rotated relative to the inner surface 13002 of the seat portion 13), so that the retaining portion 141 cannot be offset when the adjustable angle θ is adjusted or changed due to the adjustable angle θ being changed or adjusted on a horizontal plane (not on a vertical plane).

For example, as shown in FIG. 13, the seat portion 13 has at least one outer groove 13A formed on an outer surface 13001 thereof, the seat portion 13 has at least one inner groove 13B formed on the inner surface 13002 thereof, and the at least one retaining block 133 extends inwardly from the at least one outer groove 13A and the at least one inner groove 13B. In other words, the at least one outer groove 13A and the at least one inner groove 13B can be respectively formed on the outer surface 13001 and the inner surface 13002 of the seat portion 13 in advance, so that the thickness between the outer surface 13001 and the inner surface 13002 of the seat portion 13 can be decreased. Therefore, the at least one retaining block 133 and the at least one through opening 134 can be concurrently formed by a dotting or punching machine easily due to the decreased thickness between the outer surface 13001 and the inner surface 13002 of the seat portion 13. However, the foregoing example is not meant to limit the scope of the present disclosure. For another example, the at least one inner groove 13B can be omitted, so that the at least one retaining block 133 only extends inwardly from the at least one outer groove 13A. Alternatively, the at least one outer groove 13A can be omitted, so that the at least one retaining block 133 only extends inwardly from the at least one inner groove 13B.

It should be noted that a thickness h2 of the elastic portion 152 is smaller than a thickness h1 of the first fixing portion 151 as shown in FIG. 15, such that an elastic coefficient and an elastic force provided by the elastic portion 152 can be increased. Therefore, the elastic portion 152 can avoid causing elastic fatigue and plastic deformation so as to increase the usage life of the elastic member 15. In addition, the thickness h1 of the first fixing portion 151, a thickness h4 of the second fixing portion 154, and a thickness h5 of the exposed portion 155 are substantially the same, and the abutting portion 153 has an inclined chamfer 1530 formed on an end thereof.

More particularly, referring to FIG. 12, FIG. 16 and FIG. 17, the first fixing portion 151 has a front fixing section 1511, a rear fixing section 1512 connected to the elastic portion 152, and a middle fixing section 1513 connected between the front fixing section 1511 and the rear fixing section 1512. With regard to a width of the elastic member 15, as shown in FIG. 16, a width W12 of the rear fixing section 1512 is smaller than a width W11 of the front fixing section 1511, and a width W13 of the middle fixing section 1513 is decreased gradually from the front fixing section 1511 to the rear fixing section 1512. As shown in FIG. 17, a width W2 of the elastic portion 152 is much smaller than the width W12 of the rear fixing section 1512, such that an elastic coefficient and an elastic force provided by the elastic portion 152 can be increased. Therefore, the elastic portion 152 can avoid causing elastic fatigue and plastic deformation so as to increase the usage life of the elastic member 15. In addition, as shown in FIG. 17, a width W3 of the abutting portion 153 is larger than or substantially equal to a width W2 of the elastic portion 152. When the width W3 of the abutting portion 153 is larger than the width W2 of the elastic portion 152, a contact area between the elastic member 15 and the retaining member 14 is increased. It should be noted that the width W3 of the abutting portion 153 and a width W5 of the exposed portion 155 are substantially the same, and a width W4 of the second fixing portion 154 is a decreased width as shown in FIG. 16 and FIG. 17.

More particularly, referring to FIG. 12 and FIG. 15, the rear fixing section 1512 has a first fixing section 15121 connected to the middle fixing section 1513 and a second fixing section 15122 connected between the first fixing section 15121 and the elastic portion 152. With regard to a thickness of the elastic member 15, as shown in FIG. 15, a thickness h2 of the elastic portion 152 is smaller than a thickness h11 of the first fixing section 15121 and a thickness h12 of the second fixing section 15122 of the rear fixing section 1512, and the thickness h12 of the second fixing section 15122 is decreased gradually from the first fixing section 15121 to the elastic portion 152. In addition, a thickness h2 of the elastic portion 152 and a thickness h3 of the abutting portion 153 are substantially the same.

More particularly, referring to FIG. 12, FIG. 14 and FIG. 18, the seat portion 13 has a front retaining section 1301 for fixing the front fixing section 1511, a rear retaining section 1302 for fixing the rear fixing section 1512, and a middle retaining section 1303 connected between the front retaining section 1301 and the rear retaining section 1302 for fixing the middle fixing section 1513. In addition, as shown in FIG. 14, a width W2′ of the rear retaining section 1302 is smaller than a width W1′ of the front retaining section 1301, and a width W3′ of the middle retaining section 1303 is decreased gradually from the front retaining section 1301 to the rear retaining section 1302. The width W3′ of the middle retaining section 1303 and the width W2′ of the rear retaining section 1302 are smaller than the width W1′ of the front retaining section 1301, so that the friction force between the seat portion 13 and a piece of clothing can be decreased so as to increase the smooth level of the sliding assembly 1 slidably mated with the clothing. It should be noted that the seat portion 13 has an auxiliary retaining section 1304 separated from the front retaining section 1301 for fixing the second fixing portion 154 as shown in FIG. 14 and FIG. 18.

More particularly, the retaining portion 141 in a first receiving groove 131 can be restricted or limited by the bottom side surface 1332 of the at least one retaining block 133 and can be movably retained on a predetermined plane, so that the retaining member 14 can be moved upwardly (as shown in FIG. 22) or downwardly (as shown in FIG. 21) relative to the retaining portion 141 as a rotating shaft or a rotation axis. In addition, the second fixing portion 154 has a retaining body 1540 retained inside a second receiving groove 132.

Referring to FIG. 12, FIG. 20 to FIG. 22, one of the embodiments of the present disclosure provides a zipper head assembly structure Z including a sliding assembly 1 and a pulling member 2 (such as a pull tab or a pull piece). The sliding assembly 1 includes a base portion 10, a first lateral wall portion 11, a second lateral wall portion 12, a seat portion 13, a retaining member 14 and an elastic member 15. The first lateral wall portion 11 and the second lateral wall portion 12 extend respectively upwardly from two opposite lateral sides of the base portion 10, and the first lateral wall portion 11 and the second lateral wall portion 12 correspond to each other and are connected to a front side portion 101 of the base portion 10. In addition, the seat portion 13 is disposed on the base portion 10 and is connected to a rear side portion 102 of the base portion 10, and the seat portion 13 has a positioning through hole 130 formed between the first lateral wall portion 11 and the second lateral wall portion 12. Moreover, the elastic member 15 is disposed on the seat portion 13 to elastically abut against the retaining member 14, and the elastic member 15 has a first fixing portion 151 fixed on the seat portion 13, a second fixing portion 154 fixed on the seat portion 13, an exposed portion 155 connected between the first fixing portion 151 and the second fixing portion 154 and exposed out of the seat portion 13, an elastic portion 152 extending from the first fixing portion 151, and an abutting portion 153 extending from the elastic portion 152 for abutting against the retaining member 14. Furthermore, the retaining member 14 is movably disposed on the seat portion 13 for movably contacting the abutting portion 153 of the elastic member 15, and the retaining member 14 has a positioning portion 140 disposed on an end portion thereof for passing through the positioning through hole 130.

Therefore, the first fixing portion 151 and the second fixing portion 154 of the elastic member 15 are fixed on the seat portion 13, so that the bonding strength between the elastic member 15 and the seat portion 13 can be increased so as to prevent the pulling member 2 from being separated from the sliding assembly 1.

Moreover, the elastic coefficient and the elastic force provided by the elastic portion 152 can be increased by matching “the elastic member 15 having a first fixing portion 151 fixed on the seat portion 13, an elastic portion 152 extending from the first fixing portion 151, and an abutting portion 153 extending from the elastic portion 152 for abutting against the retaining member 14” and “the thickness h2 of the elastic portion 152 being smaller than the thickness h1 of the first fixing portion 151”. Therefore, the elastic portion 152 can avoid causing elastic fatigue and plastic deformation, so that the usage life of the elastic member 15 can be increased.

In conclusion, no matter how the adjustable angle θ is adjusted or changed, the retaining portion 141 can be restricted by the bottom side surface 1332 of the at least one retaining block 133 and can be movably retained on a predetermined plane without being changed by a change of the adjustable angle θ.
